Strain Rate

Definition - What does Strain Rate mean?

Strain rate is the rate of deformation caused by strain in a material within a corresponding time. This gauges the rate where distances of materials change within a respective period of time.

It involves both the rate wherein a certain material expands and shears, making it a standard measurement in the analysis of the corrosion process.

Corrosionpedia explains Strain Rate

Strain rate was first defined in 1867 by Jane LeCocq, an American metallurgist. It is the rate at which strain takes place and the time rate of strain change. It can also be measured against time, especially when evaluating the corrosion resistance of a certain material.

Strain rate involves the rate wherein a material shrinks or expands and the rate of deformation brought by progressive shearing without a change in volume.

Accurate measurement of strain rate can be highly beneficial in the field of metallurgy and corrosion engineering. Since materials may undergo deformation in various rates and directions, learning how to gauge strain rate with respect to certain elements like time, velocity and others is vital in the determination of the material strength and the point at which corrosion, specifically stress corrosion cracking, could take place.

The use of low strain rate is now a widely used technique in evaluating the response of material against stress. This must be carefully studied and implemented in the field in order to generate accurate outcomes.
